Organization Consolidation And Presentation Of Financial Statements [Abstract]

Background and Basis of Presentation

1. Background and Basis of Presentation

The Company is a leading home and security products company with a portfolio of leading branded products used for residential home repair, remodeling, new construction and security applications. References to “Fortune Brands,” “the Company,” “we,” “our” and “us” refer to Fortune Brands Home & Security, Inc. and its consolidated subsidiaries as a whole, unless the context otherwise requires.

Basis of Presentation

The consolidated financial statements in this Annual Report on Form 10-K have been derived from the accounts of the Company and its wholly-owned subsidiaries. The Company’s consolidated financial statements are based on a fiscal year ending December 31. Certain of the Company’s subsidiaries operate on a 52 or 53 week fiscal year ending during the month of December.

In the fourth quarter of 2020, our Doors & Security segment was renamed “Outdoors & Security”. The Outdoors & Security segment name change is to the name only and had no impact on the Company’s historical financial position, results of operations, cash flow or segment level results previously reported.

In December 2020, we acquired 100% of the outstanding equity of Larson Manufacturing ("Larson"), the North American market leading brand of storm, screen and security doors. Larson also sells related outdoor living products including retractable screens and porch windows. The acquisition is aligned with our strategic focus on the fast-growing outdoor living space. The Company completed the acquisition for a total purchase price of approximately $715.2 million, net of cash acquired and closing date working capital adjustments. The acquisition cost is further subject to the final post-closing working capital adjustment. We financed the transaction with borrowings under our existing credit facilities. The financial results of Larson were included in the Company’s consolidated balance sheet as of December 31, 2020. Larson's net sales, operating income and cash flows from the date of acquisition to December 31, 2020 were not material to the Company. The results of operations are included in the Outdoors & Security segment.

Accounting Policies [Abstract]

Significant Accounting Policies

2. Significant Accounting Policies

Use of Estimates The presentation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and assumptions that affect reported amounts and related disclosures. Actual results in future periods could differ from those estimates.

Cash and Cash Equivalents Highly liquid investments with an original maturity of three months or less are included in cash and cash equivalents.

Allowances for Credit Losses Trade receivables are recorded at the stated amount, less allowances for discounts and credit losses. The allowances represent estimated uncollectible receivables associated with potential customer defaults on contractual obligations (usually due to customers’ potential insolvency) or discounts related to early payment of accounts receivables by our customers. The allowances for credit losses include provisions for certain customers where a risk of default has been specifically identified. In addition, the allowances include a provision for expected customer defaults on a general formula basis when it cannot yet be associated with specific customers. Expected credit losses are estimated using various factors, including the length of time the receivables are past due, historical collection experience and existing economic conditions. In accordance with this policy, our allowance for credit losses was $6.7 million and $3.0 million as of December 31, 2020 and 2019, respectively.

Inventories Inventory provisions are recorded to reduce inventory to the net realizable dollar value for obsolete or slow moving inventory based on assumptions about future demand and marketability of products, the impact of new product introductions, inventory levels and turns, product spoilage and specific identification of items, such as product discontinuance, engineering/material changes, or regulatory-related changes.

During the fourth quarter of 2018, we determined that it was preferable to change our accounting policy from last-in, first-out (“LIFO”) to first-in, first out (“FIFO”) for product groups in which metals comprise a significant portion of inventory cost. We believe this change is preferable because it results in a uniform method to value our inventory across all our segments, improves comparability with our peers, and is expected to better reflect the current value of inventory on the consolidated balance sheets. The change in costing method, which affected our Plumbing and Outdoors & Security segments, was recognized during the fourth quarter of 2018, by adjusting the cost of inventories to FIFO, resulting in a pretax benefit of approximately $7.3 million ($5.5 million after tax) to Cost of products sold in the consolidated statements of income for the year ended December 31, 2018. There were no inventories valued using LIFO as of December 31, 2020 or 2019.

Property, Plant and Equipment Property, plant and equipment are carried at cost. Depreciation is provided, principally on a straight-line basis, over the estimated useful lives of the assets. Gains or losses resulting from dispositions are included in operating income. Betterments and renewals, which improve and extend the life of an asset, are capitalized; maintenance and repair costs are expensed as incurred. Assets held for use to be disposed of at a future date are depreciated over the remaining useful life. Assets to be sold are written down to fair value less costs to sell at the time the assets are being actively marketed for sale. Estimated useful lives of the related assets are as follows:


Buildings and leasehold improvements	15 to 40 years
Machinery and equipment	3 to 15 years
Software	3 to 7 years

Long-lived Assets In accordance with Accounting Standards Codification ("ASC") requirements for Property, Plant and Equipment, a long-lived asset (including amortizable identifiable intangible assets) or asset group held for use is tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. When such events occur, we compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of a long-lived asset or asset group. The cash flows are based on our best estimate of future cash flows derived from the most recent business projections. If this comparison indicates that there is an impairment, the amount of the impairment is calculated based on fair value. Fair value is estimated primarily using discounted expected future cash flows on a market-participant basis.

During 2020, we recorded an impairment of $3.6 million related to a long-lived asset to be disposed of in selling, general and administrative expenses. During 2019, we recorded an impairment of $1.7 million related to a long-lived asset to be disposed of in cost of products sold. No impairments of long-lived assets were recorded during 2018.

Leases Operating lease assets and operating lease liabilities are recognized based on the present value of the future lease payments over the lease term at commencement date. As most of our lease contracts do not provide an explicit interest rate, we use our incremental borrowing rate in determining the present value of future lease payments. Our incremental borrowing rates include estimates related to the impact of collateralization and the economic environment where the leased asset is located. The operating lease assets also include any prepaid lease payments and initial direct costs incurred, but exclude lease incentives received at lease commencement. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Our leases have remaining lease terms of 1 to 35 years, some of which may include options to extend or terminate the lease. Operating lease expense is recognized on a straight-line basis over the lease term.

We do not recognize leases with an initial term of twelve months or less on the balance sheet and instead recognize the related lease payments as expense in the statement of comprehensive income on a straight-line basis over the lease term. We account for lease and non-lease components as a single lease component for all asset classes. Additionally, for certain equipment leases, we apply a portfolio approach and account for multiple lease components as a single lease component.

Certain lease agreements include variable rental payments, including rental payments adjusted periodically for inflation. Variable rental payments are expensed during the period they are incurred and therefore are excluded from our lease assets and liabilities. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Business Combinations We account for business combinations under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations, which requires an allocation of the consideration we paid to the identifiable assets, intangible assets and liabilities based on the estimated fair values as of the closing date of the acquisition. The excess of the fair value of the purchase price over the fair values of these identifiable assets, intangible assets and liabilities is recorded as goodwill.

Purchased intangibles other than goodwill are initially recognized at fair value and amortized over their useful lives unless those lives are determined to be indefinite. The valuation of acquired assets will impact future operating results. The fair value of identifiable intangible assets is determined using an income approach on an individual asset basis. Specifically, we use the multi-period excess earnings method to determine the fair value of customer relationships and the relief-from-royalty approach to determine the fair value of the tradename and proprietary technology. Determining the fair value of acquired intangibles involves significant estimates and assumptions, including forecasted revenue growth rates, EBITDA margins, percentage of revenue attributable to the tradename, contributory asset charges, customer attrition rate, market-participant discount rates and the assumed royalty rates.

The determination of the useful life of an intangible asset other than goodwill is based on factors including historical tradename performance with respect to consumer name recognition, geographic market presence, market share, plans for ongoing tradename support and promotion, customer attrition rate, and other relevant factors.

Goodwill and Indefinite-lived Intangible Assets In accordance with ASC requirements for Intangibles - Goodwill and Other, goodwill is tested for impairment at least annually in the fourth quarter and written down when impaired. An interim impairment test is performed if an event occurs or conditions change that would more likely than not reduce the fair value of the reporting unit below the carrying value.

To evaluate the recoverability of goodwill, we first assess qualitative factors to determine whether it is more likely than not that goodwill is impaired. Qualitative factors include changes in volume, margin, customers and the industry. If it is deemed more likely than not that goodwill for a reporting unit is impaired, we will perform a quantitative impairment test using a weighting of the income and market approaches. For the income approach, we use a discounted cash flow model, estimating the future cash flows of the reporting units to which the goodwill relates and then discounting the future cash flows at a market-participant-derived discount rate. In determining the estimated future cash flows, we consider current and projected future levels of income based on management’s plans for that business; business trends, prospects and market and economic conditions; and market-participant considerations. Furthermore, our cash flow projections used to assess impairment of our goodwill and other intangible assets are significantly influenced by our projection for the U.S. home products market, our annual operating plans finalized in the fourth quarter of each year, and our ability to execute on various planned cost reduction initiatives supporting operating income improvements. Our projection for the U.S. home products market is inherently uncertain and is subject to a number of factors, such as employment, home prices, credit availability, new home starts and the rate of home foreclosures. For the market approach, we apply market multiples for peer groups to the current operating results of the reporting units to determine each reporting unit’s fair value. The Company’s reporting units are operating segments, or one level below operating segments when appropriate. When the estimated fair value of a reporting unit is less than its carrying value, we measure and recognize the amount of the goodwill impairment loss based on that difference.

The significant assumptions that are used to determine the estimated fair value for goodwill impairment testing include the following: third-party market forecasts of U.S. new home starts and home repair and remodel spending; management’s sales, operating income and cash flow forecasts; peer company EBITDA earnings multiples; the market-participant-based discount rate; and the perpetuity growth rate. Our estimates of reporting unit fair values are based on certain assumptions that may differ from our historical and future actual operating performance. Specifically, assumptions related to growth in the new construction and repair and remodel segments of the U.S. home products markets drive our forecasted sales growth. The market forecasts are developed using independent third-party forecasts from multiple sources. In addition, estimated future operating income and cash flow consider our historical performance at similar levels of sales volume and management’s future operating plans as reflected in annual and long-term plans that are reviewed and approved by management.

Certain of our tradenames have been assigned an indefinite life as we currently anticipate that these tradenames will contribute cash flows to the Company indefinitely. Indefinite-lived intangible assets are not amortized, but are evaluated at least annually to determine whether the indefinite useful life is appropriate. We measure the fair value of identifiable intangible assets upon acquisition and we review for impairment annually in the fourth quarter and whenever market or business events indicate there may be a potential impairment of that intangible. Impairment losses are recorded to the extent that the carrying value of the indefinite-lived intangible asset exceeds its fair value. The significant assumptions that are used to determine the estimated fair value for indefinite-lived intangible assets upon acquisition and subsequent impairment testing are forecasted revenue growth rates; the assumed royalty rates; and the market-participant discount rates. We measure fair value of our indefinite-lived tradenames using the relief-from-royalty approach which estimates the present value of royalty income that could be hypothetically earned by licensing the brand name to a third party over the remaining useful life. The determination of fair value using this technique requires the use of estimates and assumptions related to forecasted revenue growth rates, the assumed royalty rates and the market-participant discount rates. We first assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. Qualitative factors include changes in volume, customers and the industry. If it is deemed more likely than not that an intangible asset is impaired, we will perform a quantitative impairment test. See Note 5, “Goodwill and Identifiable Intangible Assets,” for additional information.

Events or circumstances that could have a potential negative effect on the estimated fair value of our reporting units and indefinite-lived tradenames include: lower than forecasted revenues, actual new construction and repair and remodel growth rates that fall below our assumptions, actions of key customers, increases in discount rates, continued economic uncertainty, higher levels of unemployment, weak consumer confidence, lower levels of discretionary consumer spending, a decrease in royalty rates and decline in the trading price of our common stock. We cannot predict the occurrence of certain events or changes in circumstances that might adversely affect the carrying value of goodwill and indefinite-lived assets.

Investments in Equity Securities In accordance with ASC requirements for investments in equity securities, we utilize the equity method to account for investments when we possess the ability to exercise significant influence, but not control, over the operating and financial policies of the investee. The ability to exercise significant influence is presumed when the investor possesses more than 20% of the voting interests of the investee. This presumption may be overcome based on specific facts and circumstances that demonstrate that the ability to exercise significant influence is restricted. In applying the equity method, we record our investment at cost and subsequently increase or decrease the carrying amount of the investment by our proportionate share of the net earnings or losses of the investee. We record dividends or other equity distributions as reductions in the carrying value of our investment.

When we do not have the ability to exercise significant influence over the operating and financial policies of the investee, we account for non-controlling investments in equity securities at fair value, with any gains or losses recognized through other income and expense. Equity securities without readily determinable fair values are recorded at cost minus impairment, plus or minus any changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer.

As of December 31, 2020, all of our investments in our strategic partners where we do not have significant influence over the investee do not have readily determinable fair values. As of December 31, 2020 and 2019, the carrying value of our investments was $3.5 million and $29.2 million, respectively, which is included in other assets within our Consolidated Balance Sheet. There were no impairments or other changes resulting from observable prices changes recorded during the years ended December 31, 2020, 2019 or 2018.

Defined Benefit Plans We have a number of pension plans in the United States, covering many of the Company’s employees. In addition, the Company provides postretirement health care and life insurance benefits to certain retirees. Service cost for 2020 relates to benefit accruals for an hourly Union group within the defined benefit plan for our Outdoors & Security segment. All other benefit accruals under our defined benefit pension plans were frozen as of, or prior to, December 31, 2016.

We record amounts relating to these plans based on calculations in accordance with ASC requirements for Compensation – Retirement Benefits, which include various actuarial assumptions, including discount rates, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. We recognize changes in the fair value of pension plan assets and net actuarial gains or losses in excess of 10 percent of the greater of the fair value of pension plan assets or each plan’s projected benefit obligation (the “corridor”) in earnings immediately upon remeasurement, which is at least annually in the fourth quarter of each year. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current economic conditions and trends. The discount rate used to measure obligations is based on a spot-rate yield curve on a plan-by-plan basis that matches projected future benefit payments with the appropriate interest rate applicable to the timing of the projected future benefit payments. The expected rate of return on plan assets is determined based on the nature of the plans’ investments, our current asset allocation and our expectations for long-term rates of return. Compensation increases reflect expected future compensation trends. For postretirement benefits, our health care trend rate assumption is based on historical cost increases and expectations for long-term increases. The cost or benefit of plan changes, such as increasing or decreasing benefits for prior employee service (prior service cost), is deferred and included in expense on a straight-line basis over the average remaining service period of the related employees. We believe that the assumptions utilized in recording obligations under our plans, which are presented in Note 14, “Defined Benefit Plans,” are reasonable based on our experience and on advice from our independent actuaries; however, differences in actual experience or changes in the assumptions may materially affect our financial position and results of operations. We will continue to monitor these assumptions as market conditions warrant.

Insurance Reserves We provide for expenses associated with workers’ compensation and product liability obligations when such amounts are probable and can be reasonably estimated. The accruals are adjusted as new information develops or circumstances change that would affect the estimated liability.

Litigation Contingencies Our businesses are subject to risks related to threatened or pending litigation and are routinely defendants in lawsuits associated with the normal conduct of business. Liabilities and costs associated with litigation-related loss contingencies require estimates and judgments based on our knowledge of the facts and circumstances surrounding each matter and the advice of our legal counsel. We record liabilities for litigation-related losses when a loss is probable and we can reasonably estimate the amount of the loss in accordance with ASC requirements for Contingencies. We evaluate the measurement of recorded liabilities each reporting period based on the then-current facts and circumstances specific to each matter. The ultimate losses incurred upon final resolution of litigation-related loss contingencies may differ materially from the estimated liability recorded at any particular balance sheet date. Changes in estimates are recorded in earnings in the period in which such changes occur.

Income Taxes In accordance with ASC requirements for Income Taxes, we establish deferred tax liabilities or assets for temporary differences between financial and tax reporting basis and subsequently adjust them to reflect changes in tax rates expected to be in effect when the temporary differences reverse. We record a valuation allowance reducing deferred tax assets when it is more likely than not that such assets will not be realized.

We record liabilities for uncertain income tax positions based on a two-step process. The first step is recognition, where we evaluate whether an individual tax position has a likelihood of greater than 50% of being sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation processes. For tax positions that are currently estimated to have a less than 50% likelihood of being sustained, no tax benefit is recorded. For tax positions that have met the recognition threshold in the first step, we perform the second step of measuring the benefit to be recorded. The actual benefits ultimately realized may differ from our estimates. In future periods, changes in facts, circumstances, and new information may require us to change the recognition and measurement estimates with regard to individual tax positions.

Changes in recognition and measurement estimates are recorded in the consolidated statement of income and consolidated balance sheet in the period in which such changes occur. As of December 31, 2020, we had liabilities for unrecognized tax benefits pertaining to uncertain tax positions totaling $96.1 million. It is reasonably possible that the unrecognized tax benefits may decrease in the range of $4.0 million to $48.1 million in the next 12 months primarily as a result of the conclusion of U.S. federal, state and foreign income tax proceedings.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) made significant changes to the U.S. Internal Revenue Code including a reduction in the corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017, an exemption from federal income tax for dividends received from foreign subsidiaries and an imposition of a one-time transition tax on the deemed repatriation of cumulative foreign earnings and profits as of December 31, 2017.

Revenue Recognition The Company recognizes revenue for the sale of goods based on its assessment of when control transfers to our customers. See Note 13, “Revenue,” for additional information.

Cost of Products Sold Cost of products sold includes all costs to make products saleable, such as labor costs, inbound freight, purchasing and receiving costs, inspection costs and internal transfer costs. In addition, all depreciation expense associated with assets used to manufacture products and make them saleable is included in cost of products sold.

Customer Program Costs Customer programs and incentives are a common practice in our businesses. Our businesses incur customer program costs to obtain favorable product placement, to promote sales of products and to maintain competitive pricing. We record estimates to reduce revenue for customer programs and incentives, which are considered variable consideration, and include price discounts, volume-based incentives, promotions and cooperative advertising when revenue is recognized in order to determine the amount of consideration the Company will ultimately be entitled to receive. These estimates are based on historical and projected experience for each type of customer. In addition, for certain customer program incentives, we receive an identifiable benefit (goods or services) in exchange for the consideration given and record the associated expenditure in selling, general and administrative expenses. Volume allowances are accrued based on management’s estimates of customer volume achievement and other factors incorporated into customer agreements, such as new products, store sell-through, merchandising support, levels of returns and customer training. Management periodically reviews accruals for these rebates and allowances, and adjusts accruals when circumstances indicate (typically as a result of a change in volume expectations). The costs typically recognized in selling, general and administrative expenses include product displays, point of sale materials and media production costs. The costs included in the selling, general and administrative expenses category were $64.7 million, $66.3 million and $66.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Selling, General and Administrative Expenses Selling, general and administrative expenses include advertising costs; marketing costs; selling costs, including commissions; research and development costs; shipping and handling costs, including warehousing costs; and general and administrative expenses. Shipping and handling costs included in selling, general and administrative expenses were $232.6 million, $225.5 million and $215.9 million in 2020, 2019 and 2018, respectively.

Advertising costs, which amounted to $259.4 million, $251.7 million and $243.6 million in 2020, 2019 and 2018, respectively, are principally expensed as incurred. Advertising costs paid to customers as pricing rebates include product displays, marketing administration costs, media production costs and point of sale materials. Advertising costs recorded as a reduction to net sales, primarily cooperative advertising, were $66.7 million, $74.0 million and $72.4 million in 2020, 2019 and 2018, respectively. Advertising costs recorded in selling, general and administrative expenses were $192.7 million, $177.7 million and $171.2 million in 2020, 2019 and 2018, respectively.

Research and development expenses include product development, product improvement, product engineering and process improvement costs. Research and development expenses, which were $49.9 million, $48.2 million and $50.3 million in 2020, 2019 and 2018, respectively, are expensed as incurred within selling, general and administrative expenses.

Stock-based Compensation Stock-based compensation expense, measured as the fair value of an award on the date of grant, is recognized in the financial statements over the period that an employee is required to provide services in exchange for the award. The fair value of each option award is measured on the date of grant using the Black-Scholes option-pricing model. The fair value of each performance share award is based on the average of the high and low share prices on the date of grant and the probability of meeting performance targets. The fair value of each restricted stock unit granted is equal to the average of the high and low share prices on the date of grant. See Note 12, “Stock-Based Compensation,” for additional information.

Earnings Per Share Earnings per common share is calculated by dividing net income attributable to Fortune Brands by the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per common share include the impact of all potentially dilutive securities outstanding during the year. See Note 20, “Earnings Per Share,” for further discussion.

Foreign Currency Translation Foreign currency balance sheet accounts are translated into U.S. dollars at the actual rates of exchange at the balance sheet date. Income and expenses are translated at the average rates of exchange in effect during the period for the foreign subsidiaries where the local currency is the functional currency. The related translation adjustments are made directly to a separate component of the “accumulated other comprehensive income” (“AOCI”) caption in equity. Transactions denominated in a currency other than the functional currency of a subsidiary are translated into functional currency with resulting transaction gains or losses recorded in other expense, net.

Derivative Financial Instruments In accordance with Accounting Standards Codification ("ASC") requirements for Derivatives and Hedging, we recognize all derivative contracts as either assets or liabilities on the balance sheet, and the measurement of those instruments is at fair value. If the derivative is designated as a fair value hedge and is effective, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings in the same period. If the derivative is designated as a cash flow hedge, the changes in the fair value of the derivative are recorded in other comprehensive income (“OCI”) and are recognized in the consolidated statement of income when the hedged item affects earnings. If the derivative is designated as an effective economic hedge of the net investment in a foreign operation, the changes in the fair value of the derivative is reported in the cumulative translation adjustment section of OCI. Similar to foreign currency translation adjustments, these changes in fair value are recognized in earnings only when realized upon sale or upon complete or substantially complete liquidation of the investment in the foreign entity.

Deferred currency (loss) gains of $(3.0) million, $4.1 million and $2.2 million (before tax impact) were reclassified into earnings for the years ended December 31, 2020, 2019 and 2018, respectively. Based on foreign exchange rates as of December 31, 2020, we estimate that $2.0 million of net derivative gain included in AOCI as of December 31, 2020 will be reclassified to earnings within the next twelve months.

Recently Issued Accounting Standards

Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, which requires lessees to recognize almost all leases on their balance sheet as “right-of-use” assets and lease liabilities but recognize related expenses in a manner similar to previous accounting guidance. The guidance also eliminates previous real estate-specific provisions for all entities. In January 2018, the FASB issued ASU 2018-01, which clarifies the application of the new leases guidance to land easements. In July 2018, the FASB issued ASU 2018-10 and ASU 2018-11, which clarify certain guidance included in ASU 2016-02 and introduces a new optional transition method, which does not require revisions to comparative periods.

We adopted this standard as of January 1, 2019 using the transition method introduced by ASU 2018-11, which does not require revisions to comparative periods. We elected to implement the transition package of practical expedients permitted within the new standard, which among other things, allows us to carryforward the historical lease classification. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases.

Adoption of the new standard resulted in the recording of lease assets and lease liabilities of approximately $177.2 million and $182.6 million, respectively, as of January 1, 2019. The difference between the lease assets and lease liabilities primarily relates to accrued rent and unamortized lease incentives recorded in accordance with the previous leasing guidance. The new standard did not materially impact our consolidated statements of income or cash flows.

Financial Instruments—Credit Losses

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, which changes the impairment model for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance applies to most financial assets measured at amortized cost, including trade and other receivables and loans as well as off-balance-sheet credit exposures (e.g., loan commitments and standby letters of credit). The standard replaced the “incurred loss” approach under the current guidance with an “expected loss” model that requires an entity to estimate its lifetime “expected credit loss.” We adopted this guidance on January 1, 2020. The adoption of this guidance did not have a material effect on our financial statements.

Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, which removed the requirement to disclose: 1) amount of and reasons for transfers between Levels 1 and 2 of the fair value hierarchy, 2) policy for timing of transfers between levels, and 3) valuation processes for Level 3 investments. In addition, this guidance modified and added other disclosure requirements, which primarily relate to valuation of Level 3 assets and liabilities. We adopted this guidance on January 1, 2020. The adoption of this guidance did not have a material effect on our financial statements.

Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

In August 2018, the FASB issued ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Costs to obtain software, including configuration and integration with legacy IT systems, coding and testing, including parallel process phases are eligible for capitalization under the new standard. In addition, activities that would be expensed include costs related to vendor demonstrations, determining performance and technology requirements and training activities. We adopted this guidance on January 1, 2020. The adoption of this guidance did not have a material effect on our financial statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU 2019-12, which is intended to simplify accounting for income taxes and improve consistency in application. ASU 2019-12 amends certain elements of income tax accounting, including but not limited to intraperiod tax allocations, step-ups in tax basis of goodwill, and calculating taxes on year-to-date losses in interim periods. The guidance is effective for the Company’s fiscal year beginning January 1, 2021, with early adoption permitted. We do not expect the adoption of this guidance to have a material effect on our financial statements.

Clarifications in Accounting for Equity Securities

In January 2020, the FASB issued ASU 2020-01, which clarifies the interactions between accounting for equity investments (ASC 321), equity method accounting (ASC 323) and derivatives and hedges (ASC 815). As a result of the ASU, when entities apply the measurement alternative to non-controlling equity investments under ASC 321, and must transition to the equity method of accounting because of an observable transaction, existing investments should be remeasured immediately before applying the equity method of accounting. Additionally, it states that if entities hold non-derivative forward contracts or purchased call options to acquire equity securities, such instruments should be measured using the fair value principles of ASC 321 before settlement or exercise. The Company early adopted this guidance on January 1, 2020, and as a result recognized non-cash gains of $11.0 million within other income in 2020 related to our investment in Flo Technologies, Inc.

Effects of Reference Rate Reform

In March 2020, the FASB issued ASU 2020-04, which provides relief from accounting analysis and impacts that may otherwise be required for modifications to agreements necessitated by reference rate reform. It also provides optional expedients to enable the continuance of hedge accounting where certain hedging relationships are impacted by reference rate reform. In January 2021, the FASB issued ASU 2021-01 which further clarifies the scope of ASU 2020-04. This optional guidance is effective immediately, and available to be used through December 31, 2022. We are assessing the impact that reference rate reform and the related adoption of this guidance may have on our financial statements.

Acquisitions and Dispositions

4. Acquisitions and Dispositions

In December 2020, we acquired 100% of the outstanding equity of Larson Manufacturing ("Larson"), the North American market leading brand of storm, screen and security doors. Larson also sells related outdoor living products including retractable screens and porch windows. The acquisition of Larson is aligned with our strategic focus on the fast-growing outdoor living space. The Company completed the acquisition for a total purchase price of approximately $715.2 million, net of cash acquired and closing date working capital adjustments. The acquisition cost is further subject to the final post-closing working capital adjustment. We financed the transaction with borrowings under our existing credit facilities. The financial results of Larson were included in the Company’s consolidated balance sheet as of December 31, 2020. Larson's net sales, operating income and cash flows from the date of acquisition to December 31, 2020 were not material to the Company. The results of operations are included in the Outdoors & Security segment. We incurred $4.5 million of Larson acquisition-related transaction costs in the year ended December 31, 2020. The goodwill expected to be deductible for income tax purposes is approximately $290 million, subject to the finalization of the purchase price allocation.

The following table summarizes the preliminary allocation of the purchase price to the fair value of assets acquired and liabilities assumed as of the date of the acquisition.

(In millions)
Accounts receivable	$	42.3
Inventories		51.7
Property, plant and equipment		66.4
Goodwill		300.9
Identifiable intangible assets		313.0
Operating lease assets		6.2

Net assets acquired^(a)	$	715.2

^(a) Net assets exclude $0.4 million of cash transferred to the Company as the result of the Larson acquisition.

The preceding purchase price allocation has been determined provisionally and is subject to revision as additional information about the fair value of individual assets and liabilities becomes available. We apply significant judgement in determining the

estimates and assumptions used to determine the fair value of the identifiable intangible assets, including forecasted revenue growth rates, EBITDA margins, percentage of revenue attributable to the tradename, contributory asset charges, customer attrition rate, market-participant discount rates and the assumed royalty rates. The Company is in the process of finalizing valuations of certain tangible and intangible assets, including property, plant and equipment and identifiable intangible assets. The provisional measurement of property, plant and equipment, identifiable intangible assets, and goodwill is subject to change. Any change in the acquisition date fair value of the acquired assets and liabilities will change the amount of the purchase price allocable to goodwill.

Goodwill includes expected sales and cost synergies. The goodwill will be included in our Outdoors & Security segment. Identifiable intangible assets consist of a finite-lived customer relationships asset of $168.0 million, an indefinite-lived tradename of $111.0 million and a finite-lived proprietary technology asset of $34.0 million. The useful life of the customer relationship intangible asset is estimated to be 13 years. The Larson tradename has been assigned an indefinite life as we currently anticipate that this tradename will contribute cash flows to the Company indefinitely. The useful life of the proprietary technology intangible asset is estimated to be 7 years. Customer and contractual relationships and proprietary technology are amortized on a straight-line basis over their useful lives.

The following unaudited pro forma summary presents consolidated financial information as if Larson had been acquired on January 1, 2019. The unaudited pro forma financial information is based on historical results of operations and financial position of the Company and Larson. The pro forma results include:

•

estimated amortization of finite-lived intangible asset, including customer relationships and proprietary technology,

•

the estimated cost of the inventory adjustment to fair value,

•

interest expense associated with debt that would have been incurred in connection with the acquisition,

•

the reclassification of Larson transaction costs from 2020 to the first quarter of 2019, and

•

the removal of certain transactions recorded in the historical financial statements of Larson related to assets and activities which were retained by the seller, and

•

adjustments to conform accounting policies.

The unaudited pro forma financial information does not necessarily represent the results that would have occurred had the acquisition occurred on January 1, 2019. In addition, the unaudited pro forma information should not be deemed to be indicative of future results.

Net sales	$	6,493.2	$	6,100.4
Net income	$	592.5	$	410.8

In 2018 our Plumbing segment entered into a strategic partnership with, and acquired non-controlling equity interests in, Flo

Technologies, Inc. (“Flo”), a U.S. manufacturer of comprehensive water monitoring and shut-off systems with leak detection

technologies. In January 2020, we entered into an agreement to acquire 100% of the outstanding shares of Flo in a multi-phase

transaction. As part of this agreement, we acquired additional shares for $44.2 million in cash, including direct transactions costs, and entered into a forward contract to purchase all remaining shares of Flo at a future date in exchange for an additional $7.9 million in cash, which is included in other assets in our condensed consolidated balance sheet. In April 2020, we acquired additional shares of Flo under a separate option agreement which resulted in a non-cash gain of $4.4 million on the forward contract as included within other income during the twelve months ended December 31, 2020.

As of December 31, 2020, we owned approximately 80% of Flo’s outstanding shares. Starting in the first quarter of 2020, we applied the equity method of accounting to our investment in Flo as the minority stockholders had substantive participating rights which precluded consolidation in our results of operations and statements of financial position and cash flows. The substantive participating rights expired on January 1, 2021, at which time we obtained control of, and began consolidating, Flo in our results. The second phase, scheduled to occur in the first quarter of 2022, will result in the acquisition of the remaining outstanding shares of Flo for a price based on a multiple of Flo’s 2021 sales and adjusted earnings before interest and taxes. Immediately prior to applying the equity method of accounting, we recognized a non-cash gain of $6.6 million within other income during the twelve months ended December 31, 2020 related to the remeasurement of our previously existing investment in Flo.

The carrying value of our investment in Flo was $76.2 million at December 31, 2020 and $25.7 million at December 31, 2019.

In September 2018, we acquired 100% of the membership interests of Fiber Composites LLC (“Fiberon”), a leading U.S. manufacturer of outdoor performance materials used in decking and railing products for a total purchase price of approximately $470.0 million, subject to certain post-closing adjustments. The acquisition of Fiberon provided category expansion and product extension opportunities into the outdoor living space for our Outdoors & Security segment. Fiberon’s net sales and operating income in 2018 were not material to the Company. We financed the transaction using cash on hand and borrowings under our

revolving credit and term loan facilities. The results of operations are included in the Outdoors & Security segment from the date of the acquisition. Goodwill related to this acquisition is deductible for income tax purposes.

We also had identifiable intangible assets, principally tradenames and customer relationships, of $1,420.3 million and $1,168.9 million as of December 31, 2020 and 2019, respectively. The $295.1 million increase in gross identifiable intangible assets was primarily due to the acquisition of Larson, partially offset by tradename impairment charges of $22.5 million in our Plumbing and Cabinets segments.

The gross carrying value and accumulated amortization by class of intangible assets as of December 31, 2020 and 2019 were as follows:

	As of December 31, 2020							As of December 31, 2019

Amortizable intangible assets, principally customer relationships, are subject to amortization on a straight-line basis over their estimated useful life, ranging from 2 to 30 years, based on the assessment of a number of factors that may impact useful life which include customer attrition rates and other relevant factors. We expect to record intangible amortization of approximately $60 million in 2021, $59 million in 2022, $58 million in 2023, $57 million in 2024, and $57 million in 2025.

During the second quarter of 2020, extended closures of luxury plumbing showrooms associated with COVID-19 led to lower than expected sales related to an indefinite-lived tradename within the Plumbing segment, which combined with the updated financial outlook compared to previous forecasts and the continued uncertainty of the pandemic on the sales and profitability related to the tradename led us to conclude that it was more likely than not that the indefinite-lived tradename was impaired. Therefore, we performed an interim impairment test as of June 30, 2020, and as a result we recognized a pre-tax impairment charge of $13.0 million related to this tradename. We also performed an evaluation of the useful life of this tradename and determined it was no longer indefinite-lived due to changes in long-term management expectations and future operating plans. As a result, the remaining carrying value of this tradename is being amortized over its estimated useful life of 30 years.

In the first quarter of 2020, we recognized an impairment charge of $9.5 million related to an indefinite-lived tradename in our Cabinets segment. This charge was primarily the result of lower expected sales of custom cabinetry products related to the impact of COVID-19. In the fourth quarter of 2019, we recognized an impairment charge of $12.0 million related to the same indefinite-lived tradename, which was the result of a strategic shift associated with new segment leadership and acceleration of our capacity rebalancing initiatives from custom cabinetry products to value-based cabinetry products as a result of lower than expected sales of custom cabinetry products compared to prior forecasts. As of December 31, 2020, the carrying value of this tradename was $29.1 million.

In the third quarter of 2019, we recognized an impairment charge of $29.5 million related to a second indefinite-lived tradename in our Cabinets segment, which was primarily the result of a continuing shift in consumer demand from semi-custom cabinetry products to value-priced cabinetry products, which led to consecutive downward adjustments of internal sales forecasts and future growth rates associated with the tradename. In the fourth quarter of 2018, we recorded an impairment charge of $35.5 million related to the same indefinite-lived tradename, which was primarily the result of lower than forecasted sales during the fourth quarter of 2018 as well as projected changes in the mix of revenue across our tradenames in future periods, including the impact of more moderate industry growth expectations, which were finalized during our annual planning process conducted during the fourth quarter of 2018. As of December 31, 2020, the carrying value of this tradename was $85.0 million.

During the third quarter of 2018, we recorded a pre-tax impairment charge of $27.1 million related to a third indefinite-lived tradename within the Cabinets segment. This charge was primarily the result of reduced revenue growth expectations associated with Cabinets operations in Canada, including the announced closure of Company-owned retail locations. As of December 31, 2020, the carrying value of this tradename was $39.8 million.

The fair values of the impaired tradenames were measured using the relief-from-royalty approach, which estimates the present value of royalty income that could be hypothetically earned by licensing the tradename to a third party over its remaining useful life. Some of the more significant assumptions inherent in estimating the fair values include forecasted revenue growth rates, assumed royalty rates, and market-participant discount rates that reflect the level of risk associated with the tradenames’ future revenues and profitability. We selected the assumptions used in the financial forecasts using historical data, supplemented by current and anticipated market conditions, estimated growth rates, and management plans. These assumptions represent level 3 inputs of the fair value hierarchy (refer to Note 9).

The significant assumptions used to estimate the fair values of the tradenames impaired during the years ended December 31, 2020 and 2019 were as follows:

	2020									2019
Unobservable Input	Minimum			Maximum			Weighted Average^(a)			Minimum			Maximum			Weighted Average^(a)
Discount rates		14.8	%		15.8	%		15.1	%		13.0	%		13.5	%		13.3	%
Royalty rates^(b)		4.0	%		5.0	%		4.3	%		3.0	%		4.0	%		3.3	%
Long-term revenue growth rates^(c)		1.0	%		3.0	%		1.6	%		3.0	%		3.0	%		3.0	%

⁽^a) Weighted by relative fair value of the impaired tradenames.

^(b) Represents estimated percentage of sales a market-participant would pay to license the impaired tradenames.

^(c)Selected long-term revenue growth rate within 10-year projection period of the impaired tradenames.

As of December 31, 2020, the fair value of four Cabinets' tradenames exceeded their carrying values of $180.6 million by less than 30%. A reduction in the estimated fair value of the tradenames in our Cabinets segment could trigger additional impairment charges in future periods. Events or circumstances that could have a potential negative effect on the estimated fair value of our reporting units and indefinite-lived tradenames include: lower than forecasted revenues, more severe impacts of the COVID-19 pandemic than currently expected, actual new construction and repair and remodel growth rates that fall below our assumptions, actions of key customers, increases in discount rates, continued economic uncertainty, higher levels of unemployment, weak consumer confidence, lower levels of discretionary consumer spending, a decrease in royalty rates and a decline in the trading price of our common stock. We cannot predict the occurrence of certain events or changes in circumstances that might adversely affect the carrying value of goodwill and indefinite-lived assets.

Unsecured Senior Notes

At December 31, 2020, the Company had aggregate outstanding notes in the principal amount of $1.8 billion, with varying maturities (the “Notes”). The Notes are unsecured senior obligations of the Company. The following table provides a summary of the Company’s outstanding Notes, including the carrying value of the Notes, net of underwriting commissions, price discounts, and debt issuance costs as of December 31, 2020 and December 31, 2019:

(in millions)					Net Carrying Value

Total Senior Notes					$	1,787.2	$	2,184.3

During June 2020, we repaid all outstanding 3.000% Senior Notes issued in June 2015 at their maturity date using borrowings under our 2019 Revolving Credit Agreement (as defined below). In September 2019, we issued $700 million of 3.25% Senior Notes due 2029 (“2019 Notes”) in a registered public offering. The Company used the proceeds from the 2019 Notes offering to repay in full the Company’s $350 million term loan and to pay down outstanding balances under our revolving credit facility.

In September 2018, we issued $600 million of unsecured senior notes (“2018 Notes”) in a registered public offering. The 2018 Notes are due in 2023 with a coupon rate of 4%. We used the proceeds from the 2018 Notes offering to pay down our revolving credit facility.

Notes payments due during the next five years as of December 31, 2020 are zero in 2021 through 2022, $600 million in 2023, zero in 2024 and $500 million in 2025.

Credit Facilities

In April 2020, the Company entered into a supplemental 364-day, $400 million revolving credit facility (the “2020 Revolving Credit Agreement”), and borrowings thereunder will be used for general corporate purposes.

In September 2019, the Company entered into a second amended and restated $1.25 billion revolving credit facility (the “2019 Revolving Credit Agreement”), and borrowings thereunder will be used for general corporate purposes. The terms and conditions of the 2019 Revolving Credit Agreement, including the total commitment amount, essentially remained the same as under the previous credit agreement, except that the maturity date was extended to September 2024. Borrowings amounting to $165.0 million were rolled-over from the prior revolving credit facility into the 2019 Revolving Credit Agreement. Interest rates under the 2019 Revolving Credit Agreement are variable based on LIBOR at the time of the borrowing and the Company’s long-term credit rating and can range from LIBOR + 0.91% to LIBOR + 1.4%. The amendment also includes a covenant under which the Company is required to maintain a minimum ratio of consolidated EBITDA to consolidated interest expense of 3.0 to 1.0. Adjusted EBITDA is defined as consolidated net income before interest expense, income taxes, depreciation, amortization of intangible assets, losses from asset impairments, and certain other one-time adjustments. In addition, the amendment includes a covenant under which the Company’s ratio of consolidated debt minus certain cash and cash equivalents to consolidated EBITDA generally may not exceed 3.5 to 1.0. This amendment and restatement of the credit agreement was a non-cash transaction for the Company. On December 31, 2020 and December 31, 2019, our outstanding borrowings under these credit facilities were $785.0 million and zero, respectively, which is included in Long-term debt in the condensed consolidated balance sheets. As of December 31, 2020, we were in compliance with all covenants under this facility.

We currently have uncommitted bank lines of credit in China, which provide for unsecured borrowings for working capital of up to $17.5 million in aggregate as of December 31, 2020 and December 31, 2019, of which there were no outstanding balances as of December 31, 2020 and 2019. The weighted-average interest rates on these borrowings were zero in both 2020 and 2019.

The components of long-term debt were as follows:

(In millions)	2020		2019
Notes	$	1,787.2	$	2,184.3
$1,250 million revolving credit agreement due September 2024		785.0		—

Less: current portion		—		399.7
Total long-term debt	$	2,572.2	$	1,784.6

In our debt agreements, there are normal and customary events of default which would permit the lenders to accelerate the debt if not cured within applicable grace periods, such as failure to pay principal or interest when due or a change in control of the Company. There were no events of default as of December 31, 2020.

Financial Instruments

8. Financial Instruments

We do not enter into financial instruments for trading or speculative purposes. We principally use financial instruments to reduce the impact of changes in foreign currency exchange rates and commodities used as raw materials in our products. The principal derivative financial instruments we enter into on a routine basis are foreign exchange contracts. Derivative financial instruments are recorded at fair value. The counterparties to derivative contracts are major financial institutions. We are subject to credit risk on these contracts equal to the fair value of these instruments. Management currently believes that the risk of incurring material losses is unlikely and that the losses, if any, would be immaterial to the Company.

Raw materials used by the Company are subject to price volatility caused by weather, supply conditions, geopolitical and economic variables, and other unpredictable external factors. As a result, from time to time, we enter into commodity swaps to manage the price risk associated with forecasted purchases of materials used in our operations. We account for these commodity derivatives as economic hedges or cash flow hedges. Changes in the fair value of economic hedges are recorded directly into current period earnings. The gross notional amount of all commodity derivatives outstanding at December 31, 2020 was $9.8 million, representing a net settlement asset of $1.9 million. There were no material commodity derivative contracts outstanding for the year ended December 31, 2019.

We may enter into foreign currency forward contracts to protect against foreign exchange risks associated with certain existing assets and liabilities, forecasted future cash flows, and net investments in foreign subsidiaries. Foreign exchange contracts related to forecasted future cash flows correspond to the periods of the forecasted transactions, which generally do not exceed 12 to 15 months subsequent to the latest balance sheet date.

For derivative instruments that are designated as fair value hedges, the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item, are recognized on the same line of the statement of income. The changes in the fair value of cash flow hedges are reported in OCI and are recognized in the statement of income when the hedged item affects earnings. The changes in fair value for net investment hedges are recognized in the statement of income when realized upon sale or upon complete or substantially complete liquidation of the investment in the foreign entity. In addition, changes in the fair value of all economic hedge transactions are immediately recognized in current period earnings. Our primary foreign currency hedge contracts pertain to the Canadian dollar, the British pound, the Mexican peso and the Chinese yuan. The gross U.S. dollar equivalent notional amount of all foreign currency derivative hedges outstanding at December 31, 2020 was $415.2 million, representing a net settlement liability of $2.8 million. Based on foreign exchange rates as of December 31, 2020, we estimate that $2.0 million of net derivative gains included in accumulated other comprehensive income as of December 31, 2020 will be reclassified to earnings within the next twelve months.

The fair values of foreign exchange and commodity derivative instruments on the consolidated balance sheets as of December 31, 2020 and 2019 were:

Fair Value Disclosures [Abstract]

Fair Value Measurements

9. Fair Value Measurements

ASC requirements for Fair Value Measurements and Disclosures establish a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels. Level 1 inputs, the highest priority, are quoted prices in active markets for identical assets or liabilities. Level 2 inputs reflect other than quoted prices included in level 1 that are either observable directly or through corroboration with observable market data. Level 3 inputs are unobservable inputs due to little or no market activity for the asset or liability, such as internally-developed valuation models. We do not have any assets or liabilities measured at fair value on a recurring basis that are level 3, except for pension assets discussed in Note 14.

The carrying value and fair value of debt as of December 31, 2020 and 2019 were as follows:

(In millions)	December 31, 2020				December 31, 2019
	Carrying Value		Fair Value		Carrying Value		Fair Value
Notes, net of underwriting commissions, price discounts and debt issuance costs	$	1,787.2	$	1,994.9	$	2,184.3	$	2,271.4
Revolving credit facility		785.0		785.0		—		—

The estimated fair value of our revolving credit facility is determined primarily using broker quotes, which are level 2 inputs. The estimated fair value of our Notes is determined by using quoted market prices of our debt securities, which are level 1 inputs.

Assets and liabilities measured at fair value on a recurring basis as of December 31, 2020 and 2019 were as follows:

(In millions)	Fair Value
	2020		2019
Assets:
Derivative asset financial instruments (level 2)	$	5.6	$	3.0
Deferred compensation program assets (level 2)		16.3		12.1
Total assets	$	21.9	$	15.1
Liabilities:
Derivative liability financial instruments (level 2)	$	6.5	$	2.5

The principal derivative financial instruments we enter into on a routine basis are foreign exchange contracts. In addition, from time to time, we enter into commodity swaps. Derivative financial instruments are recorded at fair value.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock-Based Compensation

12. Stock-Based Compensation

As of December 31, 2020, we had awards outstanding under two Long-Term Incentive Plans, the Fortune Brands Home & Security, Inc. 2013 Long-Term Incentive Plan (the “Plan”) and the 2011 Long-Term Incentive Plan (the “2011 Plan”, and together with the Plan - the “Plans”). No new stock-based awards can be made under the 2011 Plan, but there are outstanding stock options under the 2011 Plan that continue to be exercisable. Our stockholders approved the Plan in 2013, which provides for the granting of stock options, performance share awards, restricted stock units, and other equity-based awards, to employees, directors and consultants. As of December 31, 2020, approximately 2.7 million shares of common stock remained authorized for issuance under the Plan. In addition, shares of common stock that were granted and subsequently expired, terminated, cancelled or forfeited, or were used to satisfy the required withholding taxes with respect to existing awards under the Plans may be recycled back into the total numbers of shares available for issuance under the Plan. Upon the exercise or payment of stock-based awards, shares of common stock are issued from authorized common shares.

Stock-based compensation expense was as follows:

(In millions)	2020		2019		2018
Restricted stock units	$	21.5	$	19.4	$	21.3
Stock option awards		5.3		7.0		8.6
Performance awards		22.6		4.2		6.3
Director awards		0.9		1.2		1.0
Total pre-tax expense		50.3		31.8		37.2
Tax benefit		8.7		6.0		6.2
Total after tax expense	$	41.6	$	25.8	$	31.0

Included in compensation costs are cash-settled restricted stock units of $2.3 million, $1.4 million and $0.9 million that are classified as a liability as of December 31, 2020, 2019 and 2018, respectively. Compensation costs that were capitalized in inventory were not material.

Restricted Stock Units

Restricted stock units (“RSUs”) have been granted to officers and certain employees of the Company and represent the right to receive shares of Company common stock subject to continued employment through each vesting date. RSUs generally vest ratably over a three-year period. In addition, certain employees can elect to defer receipt of a portion of their RSU awards upon vesting. Compensation cost is recognized over the service period. We calculate the fair value of each RSU granted by using the average of the high and low share prices on the date of grant.

A summary of activity with respect to RSUs outstanding under the Plans for the year ended December 31, 2020 was as follows:

	Number of Restricted Stock Units			Weighted-Average Grant-Date Fair Value
Non-vested at December 31, 2019		756,482		$	53.89
Granted		371,513			70.66
Vested		(363,146	)		56.09
Forfeited		(56,511	)		53.89
Non-vested at December 31, 2020		708,338		$	61.48

The remaining unrecognized pre-tax compensation cost related to RSUs at December 31, 2020 was approximately $23.1 million, and the weighted-average period of time over which this cost will be recognized is 1.9 years. The fair value of RSUs that vested during 2020, 2019 and 2018 was $24.0 million, $15.2 million and $22.2 million, respectively.

Stock Option Awards

Stock options were granted to officers and certain employees of the Company and represent the right to purchase shares of Company common stock subject to continued employment through each vesting date. Stock options granted under the Plans generally vest over a three-year period and generally have a maturity of ten years from the grant date.

All stock-based compensation to employees is required to be measured at fair value and expensed over the requisite service period. We recognize compensation expense on awards on a straight-line basis over the requisite service period for the entire award.

The fair value of Fortune Brands options was estimated at the date of grant using a Black-Scholes option pricing model with the assumptions shown in the following table:

	2020			2019			2018
Current expected dividend yield		1.4	%		1.5	%	1.3%
Expected volatility		25.9	%		27.0	%	24.0%
Risk-free interest rate		1.2	%		2.5	%	2.6%
Expected term	5.3 years			5.0 years			5.0 years

Beginning in 2020, the determination of expected volatility is based on the volatility of Fortune Brands common stock. The determination of expected volatility in prior years is based on a blended peer group volatility for companies in similar industries, at a similar stage of life and with similar market capitalization. The risk-free interest rate is based on U.S. government issues with a remaining term equal to the expected life of the stock options. The expected term is the period over which our employees are expected to hold their options. The expected term was determined based on the historical employee exercise behavior and the contractual term of the options. The dividend yield is based on the Company’s estimated dividend over the expected term. The weighted-average grant date fair value of stock options granted under the Plans during the years ended December 31, 2020, 2019 and 2018 was $15.21, $11.36 and $14.14, respectively.

A summary of Fortune Brands stock option activity related to Fortune Brands and former employees of Fortune Brands, Inc., the Company from which we spun off from in 2011, for the year ended December 31, 2020 was as follows:

	Options			Weighted- Average Exercise Price
Outstanding at December 31, 2019		3,825,216		$	45.27
Granted		530,932			70.56
Exercised		(1,734,610	)		37.44
Expired/forfeited		(82,509	)		56.40
Outstanding at December 31, 2020		2,539,029		$	55.54

Options outstanding and exercisable at December 31, 2020 were as follows:

	Options Outstanding ^(a)						Options Exercisable^(b)
Range Of Exercise Prices	Options Outstanding		Weighted- Average Remaining Contractual Life		Weighted- Average Exercise Price		Options Exercisable		Weighted- Average Exercise Price
13.00 to 20.00		64,274		0.75		17.21		64,274		17.21

^(a)	^{At December 31, 2020, the aggregate intrinsic value of options outstanding was $76.6 million.}

^(b)	^{At December 31, 2020 the weighted-average remaining contractual life of options exercisable was 5.7 years and the aggregate intrinsic value of options exercisable was $56.5 million.}

The remaining unrecognized compensation cost related to unvested awards at December 31, 2020 was $6.7 million, and the weighted-average period of time over which this cost will be recognized is 2.0 years. The fair value of options that vested during the years ended December 31, 2020, 2019 and 2018 was $9.4 million, $7.1 million and $6.7 million, respectively. The intrinsic value of Fortune Brands stock options exercised in the years ended December 31, 2020, 2019 and 2018 was $64.0 million, $26.0 million and $8.7 million, respectively.

Performance Share Awards

Performance share awards were granted to officers and certain employees of the Company and represent the right to earn shares of Company common stock based on the achievement of company-wide non-GAAP performance conditions, including average return on net tangible assets and cumulative EBITDA during the three-year performance period. Compensation cost is amortized into expense over the performance period, which is generally three years, and is based on the probability of meeting performance targets. The fair value of each performance share award is based on the average of the high and low stock price on the date of grant.

The following table summarizes information about performance share awards as of December 31, 2020, as well as activity during the year then ended. The number of performance share awards granted are shown below at the target award amounts:

	Number of Performance Share Awards			Weighted-Average Grant-Date Fair Value
Non-vested at December 31, 2019		555,657		$	53.71
Granted		192,958			68.15
Vested		(60,048	)		58.08
Forfeited		(112,108	)		56.32
Non-vested at December 31, 2020		576,459		$	57.54

The remaining unrecognized pre-tax compensation cost related to performance share awards at December 31, 2020 was approximately $19.9 million, and the weighted-average period of time over which this cost will be recognized is 1.7 years. The fair value of performance share awards that vested during 2020 was $4.3 million (60,048 shares).

Director Awards

Stock awards are used as part of the compensation provided to outside directors under the Plan. Awards are issued annually in the second quarter. In addition, outside directors can elect to have director cash compensation paid in stock or can elect to defer payment of stock. Compensation cost is expensed at the time of an award based on the fair value of a share at the date of the award. In 2020, 2019 and 2018, we awarded 20,181, 21,746 and 19,109 shares of Company common stock to outside directors with a weighted-average fair value on the date of the award of $46.82, $54.48 and $54.93, respectively.

Revenue From Contract With Customer [Abstract]

Revenue

13. Revenue

Our principal performance obligations are the sale of faucets and accessories, fiberglass and steel entry-door systems and locks, safes, safety, security devices and decking, and kitchen and bath cabinets (collectively, “goods” or “products”). We recognize revenue for the sale of goods based on our assessment of when control transfers to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods to our customers. Payment terms on our product sales normally range from 30 to 90 days. Taxes assessed by a governmental authority that we collect are excluded from revenue. The expected costs associated with our contractual warranties will continue to be recognized as expense when the products are sold. See Note 17, “Product Warranties,” for further discussion.

We record estimates to reduce revenue for customer programs and incentives, which are considered variable consideration, and include price discounts, volume-based incentives, promotions and cooperative advertising when revenue is recognized in order to determine the amount of consideration the Company will ultimately be entitled to receive. These estimates are based on historical and projected experience for each type of customer. In addition, for certain customer program incentives, we receive an identifiable benefit (goods or services) in exchange for the consideration given and record the associated expenditure in selling, general and administrative expenses.

We account for shipping and handling costs that occur after the customer has obtained control of a product as a fulfillment activity (i.e., as an expense) rather than as a promised service (i.e., as a revenue element). These costs are classified within selling, general and administrative expenses.

Settlement of our outstanding accounts receivable balances is normally within 30 to 90 days of the original sale transaction date. Obligations arise for us from customer rights to return our goods for any reason, including among others, product obsolescence, stock rotations, trade-in agreements for newer products and upon termination of a customer contract. We estimate future product returns at the time of sale based on historical experience and record a corresponding refund obligation, which amounted to $30.5 million and $16.9 million as of December 31, 2020 and 2019, respectively. Refund obligations are classified within other current liabilities in our consolidated balance sheet. Return assets related to the refund obligation are measured at the carrying amount of the goods at the time of sale, less any expected costs to recover the goods and any expected reduction in value. Return assets are classified within other current assets and were approximately $2.9 million and $2.6 million as of December 31, 2020 and 2019, respectively.

The Company disaggregates revenue from contracts with customers into (i) major sales distribution channels in the U.S. and (ii) total sales to customers outside the U.S. market as these categories depict the nature, amount, timing and uncertainty of revenues and cash flows that are affected by economic factors. The following table disaggregates our consolidated revenue by major sales distribution channels for the years ended December 31, 2020, 2019 and 2018.

Practical Expedients

Incremental costs of obtaining a contract include only those costs the Company incurs that would not have been incurred if the contract had not been obtained. These costs are required to be recognized as assets and amortized over the period that the related goods or services transfer to the customer. As a practical expedient, we expense as incurred costs to obtain a contract when the expected amortization period is one year or less. These costs are recorded within selling, general and administrative expenses.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Compensation And Retirement Disclosure [Abstract]

Defined Benefit Plans

Dec. 31, 2020

Defined Benefit Plans

14. Defined Benefit Plans

We have a number of pension plans in the United States, covering many of the Company’s employees; however, the majority of these plans have been frozen to new participants and benefit accruals were frozen for active participants on December 31, 2016. The plans provide for payment of retirement benefits, mainly commencing between the ages of 55 and 65. After meeting certain qualifications, an employee acquires a vested right to future benefits. The benefits payable under the plans are generally determined on the basis of an employee’s length of service and/or earnings. Employer contributions to the plans are made, as necessary, to ensure legal funding requirements are satisfied. Also, from time to time, we may make contributions in excess of the legal funding requirements. Service cost for 2020 relates to benefit accruals for an hourly Union group within the defined benefit plan for our Outdoors & Security segment. All other benefit accruals under our defined benefit pension plans were frozen as of, or prior to, December 31, 2016.

Net actuarial gains and losses occur when actual experience differs from any of the assumptions used to value defined benefit plans or when assumptions change as they may each year. The primary factors contributing to actuarial gains and losses are changes in the discount rate used to value obligations as of the measurement date and the differences between expected and actual returns on pension plan assets.

In addition, the Company provides postretirement health care and life insurance benefits to certain retirees.

^{Related to the Larson acquisition discussed in Note 4}^.

The actuarial loss is primarily a result of changes in discount rates from year to year.

The accumulated benefit obligation exceeds the fair value of assets for all pension plans. Amounts recognized in the consolidated balance sheets consist of:

	Pension Benefits						Postretirement Benefits

Net amount recognized	$	(148.6	)	$	(199.9	)	$	(13.4	)	$	(3.6	)

As of December 31, 2020, we adopted the new Society of Actuaries MP-2020 mortality tables resulting in an immaterial decrease in plan benefit obligation and ongoing expenses. As of December 31, 2019, we adopted the new Society of Actuaries MP-2019 mortality tables, resulting in an immaterial increase in plan benefit obligation, and deferred actuarial losses in accumulated other comprehensive income.

The amounts in accumulated other comprehensive loss on the consolidated balance sheets that have not yet been recognized as components of net periodic benefit cost were as follows:

Plan Assets

The fair value of the pension assets by major category of plan assets as of December 31, 2020 and 2019 were as follows:

(In millions)	Total as of balance sheet date
	2020		2019
Group annuity/insurance contracts (level 3)	$	24.8	$	24.2
Collective trusts:
Cash and cash equivalents		16.0		7.8

Fixed income		410.0		355.0
Multi-strategy hedge funds		24.6		23.2
Real estate		21.9		21.7
Total	$	784.9	$	677.2

A reconciliation of Level 3 measurements was as follows:

	Group annuity/ insurance contracts
(In millions)	2020		2019
January 1	$	24.2	$	23.6
Actual return on assets related to assets still held		0.6		0.6
December 31	$	24.8	$	24.2

Our defined benefit plans Master Trust own a variety of investment assets. All of these investment assets, except for group annuity/insurance contracts are measured using net asset value per share as a practical expedient per ASC 820. Following the retrospective adoption of ASU 2015-07 (Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share) we excluded all investments measured using net asset value per share in the amount of $760.1 million and $653.0 million as of December 31, 2020 and 2019, respectively, from the tabular fair value hierarchy disclosure.

The terms and conditions for redemptions vary for each class of the investment assets valued at net asset value per share as a practical expedient. Real estate assets may be redeemed quarterly with a 45 day redemption notice period. Investment assets in multi-strategy hedge funds may be redeemed semi-annually with a 95 day redemption notice period. Equity, fixed income and cash and cash equivalents have no specified redemption frequency and notice period and may be redeemed daily. As of December 31, 2020 we do not have an intent to sell or otherwise dispose of these investment assets at prices different than the net asset value per share.

Our investment strategy is to optimize investment returns through a diversified portfolio of investments, taking into consideration underlying plan liabilities and asset volatility. The defined benefit asset allocation policy of the plans allow for an equity allocation of 0% to 75%, a fixed income allocation of 25% to 100%, a cash allocation of up to 25% and other investments of up to 20%. Asset allocations are based on the underlying liability structure. All retirement asset allocations are reviewed periodically to ensure the allocation meets the needs of the liability structure.

Our 2021 expected blended long-term rate of return on plan assets of 4.5% was determined based on the nature of the plans’ investments, our current asset allocation and projected long-term rates of return from pension investment consultants.

Estimated Future Retirement Benefit Payments

The following retirement benefit payments are expected to be paid:

(In millions)	Pension Benefits		Postretirement Benefits
2021	$	42.0	$	1.0
2022		43.1		0.9
2023		44.2		0.9
2024		45.3		1.0
2025		46.3		1.1
Years 2026-2030		238.7		5.7

Estimated future retirement benefit payments above are estimates and could change significantly based on differences between actuarial assumptions and actual events and decisions related to lump sum distribution options that are available to participants in certain plans.

Defined Contribution Plan Contributions

We sponsor a number of defined contribution plans. Contributions are determined under various formulas. Cash contributions by the Company related to these plans amounted to $36.7 million, $36.3 million and $29.5 million in 2020, 2019 and 2018, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

15. Income Taxes

The components of income from continuing operations before income taxes and noncontrolling interests were as follows:

(In millions)	2020		2019		2018
Domestic operations	$	576.8	$	438.2	$	456.7
Foreign operations		154.0		137.1		80.3
Income before income taxes and noncontrolling interests	$	730.8	$	575.3	$	537.0

Income tax expense in the consolidated statement of income consisted of the following:

(In millions)	2020			2019			2018
Current
Federal	$	100.0		$	94.9		$	93.5
Foreign		55.9			35.1			26.4
State and other		27.5			21.5			24.1
Deferred
Federal		(1.8	)		(6.9	)	3.2
Foreign		(11.5	)		(3.1	)		(1.8	)
State and Local		(1.3	)		2.5			1.6
Total income tax expense	$	168.8		$	144.0		$	147.0

A reconciliation between the federal statutory tax rate and the effective tax rate is as follows:

(In millions)	2020			2019			2018
Income tax expense computed at federal statutory income tax rate	$	153.5		$	120.8		$	112.8
Other income taxes, net of federal tax benefit		22.3			18.0			13.7
Foreign taxes at a different rate than U.S. federal statutory income tax rate		3.0			1.4			3.5
Provision for foreign earnings repatriation, net		3.2			0.4			0.6
Net adjustments for uncertain tax positions		(0.2	)		7.5			4.1
Share-based compensation (ASU 2016-09)		(11.5	)		(3.7	)		(2.1	)
2017 Tax Act impact		—			—			5.5
Deferred tax impact of state tax rate changes		(0.7	)		3.1			3.5
Valuation allowance (decrease) increase		(7.1	)		3.4			3.0
Expiration of loss carryforwards		6.1			—			—
Miscellaneous other, net		0.2			(6.9	)		2.4
Income tax expense as reported	$	168.8		$	144.0		$	147.0
Effective income tax rate		23.1	%		25.0	%		27.4	%

The 2020 effective income tax rate was unfavorably impacted by state, local and foreign taxes, and was favorably impacted by a benefit related to share-based compensation.

The 2019 and 2018 effective income tax rates were unfavorably impacted by state, local and foreign taxes, a valuation allowance increase, and increases in uncertain tax positions. The 2018 effective income tax rate was also unfavorably impacted by an adjustment to the provisional net benefit recorded in 2017 under the Tax Act. The 2019 and 2018 effective income tax rates were favorably impacted by a benefit related to share-based compensation.

The Tax Act, enacted on December 22, 2017, made significant changes to the U.S. Internal Revenue Code including a reduction in the corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017, an exemption from federal income tax for dividends received from foreign subsidiaries and an imposition of a one-time transition tax on the deemed repatriation of cumulative foreign earnings as of December 31, 2017.

A reconciliation of the beginning and ending amount of unrecognized tax benefits (“UTBs”) is as follows:

(In millions)	2020			2019			2018
Unrecognized tax benefits—beginning of year	$	88.0		$	83.5		$	87.5
Gross additions—current year tax positions		7.2			9.2			9.1
Gross additions—prior year tax positions		3.7			2.9			9.3
Gross additions (reductions)—purchase accounting adjustments		12.1			—			1.0
Gross reductions—prior year tax positions		(11.7	)		(6.9	)		(14.5	)
Gross reductions—settlements with taxing authorities		(3.2	)		(0.7	)		(8.9	)
Unrecognized tax benefits—end of year	$	96.1		$	88.0		$	83.5

The amount of UTBs that, if recognized as of December 31, 2020, would affect the Company’s effective tax rate was $80.0 million. It is reasonably possible that, within the next twelve months, total UTBs may decrease in the range of $4.0 million to $48.1 million primarily as a result of the conclusion of U.S. federal, state and foreign income tax proceedings.

We classify interest and penalty accruals related to UTBs as income tax expense. In 2020, 2019 and 2018, we recognized interest and penalty expense of approximately $0.7 million, $3.0 million and $2.2 million, respectively. At December 31, 2020 and 2019, we had accruals for the payment of interest and penalties of $17.6 million and $16.1 million, respectively.

We file income tax returns in the U.S., various state and foreign jurisdictions. The Company is currently under examination by the U.S. Internal Revenue Service for the periods related to 2017 and 2018. In addition to the U.S., we have tax years that remain open and subject to examination by tax authorities in the following major taxing jurisdictions: Canada for years after 2015, Mexico for years after 2015 and China for years after 2016.

The components of net deferred tax assets (liabilities) as of December 31, 2020 and 2019 were as follows:

(In millions)	2020			2019
Deferred tax assets:
Compensation and benefits	$	43.3		$	37.6
Defined benefit plans		38.9			50.8
Capitalized inventories		18.4			18.2
Accounts receivable		16.0			5.1
Operating lease liabilities		43.3			42.0
Other accrued expenses		79.7			58.8
Net operating loss and other tax carryforwards		14.4			22.4
Valuation allowance		(9.7	)		(16.8	)
Miscellaneous		1.2			3.9
Total deferred tax assets		245.5			222.0
Deferred tax liabilities:
Fixed assets		(86.4	)		(70.4	)
Intangible assets		(220.9	)		(222.9	)
Operating lease assets		(43.3	)		(42.0	)
Other investments		(6.8	)		(7.4	)
Miscellaneous		(17.8	)		(19.2	)
Total deferred tax liabilities		(375.2	)		(361.9	)
Net deferred tax liability	$	(129.7	)	$	(139.9	)

In accordance with ASC requirements for Income Taxes, deferred taxes were classified in the consolidated balance sheets as of December 31, 2020 and 2019 as follows:

(In millions)	2020			2019
Other assets		30.8			17.3
Deferred income taxes		(160.5	)		(157.2	)
Net deferred tax liability	$	(129.7	)	$	(139.9	)

As of December 31, 2020 and 2019, the Company had deferred tax assets relating to net operating losses, capital losses, and other tax carryforwards of $14.4 million and $22.4 million, respectively, of which approximately $0.6 million will expire between 2021 and 2025, and the remainder of which will expire in 2026 and thereafter.

The Company has provided a valuation allowance to reduce the carrying value of certain of these deferred tax assets, as management has concluded that, based on the available evidence, it is more likely than not that the deferred tax assets will not be fully realized. During 2020, certain loss carryforwards expired, and as a result, the valuation allowance associated with these loss carryforwards also decreased.

The Company has adjusted the 2019 deferred tax components to include operating lease assets and liabilities on a gross basis for comparative purposes. The impact to 2019 was not material.

Accumulated foreign earnings and profits of the Company’s foreign subsidiaries as of December 31, 2017 were subject to a deemed repatriation tax and should not be subject to additional U.S. federal income tax upon an actual repatriation of these earnings. As of December 31, 2020, the Company has recorded an estimated deferred tax liability of $7.2 million for foreign and state taxes that will be payable upon distribution of these earnings.

Subsequent to December 31, 2017, we consider the unremitted earnings of certain foreign subsidiaries that impose local country taxes on dividends to be indefinitely reinvested. We have not provided deferred taxes on the remaining book over tax outside basis difference of $126 million related to these subsidiaries. The amount of unrecognized deferred tax liabilities for local country withholding taxes that would be owed related to these earnings is less than $7 million.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Loss Contingency [Abstract]

Contingencies

22. Contingencies

Litigation

The Company is a defendant in lawsuits that are ordinary routine litigation matters incidental to its businesses. It is not possible to predict the outcome of the pending actions, and, as with any litigation, it is possible that these actions could be decided unfavorably to the Company. The Company believes that there are meritorious defenses to these actions and that these actions will not have a material adverse effect upon the Company’s results of operations, cash flows or financial condition, and, where appropriate, these actions are being vigorously contested. Accordingly, the Company believes the likelihood of material loss is remote.

Environmental

Compliance with federal, state and local laws regulating the discharge of materials into the environment, or otherwise relating to the protection of the environment, did not have a material effect on capital expenditures, earnings or the competitive position of Fortune Brands. We are involved in remediation activities to clean up hazardous wastes as required by federal and state laws. Liabilities for remediation costs of each site are based on our best estimate of undiscounted future costs, excluding possible insurance recoveries or recoveries from other third parties. Uncertainties about the status of laws, regulations, technology and information related to individual sites make it difficult to develop estimates of future environmental remediation exposures. Some of the potential liabilities relate to sites we own, and some relate to sites we no longer own or never owned. Several of our subsidiaries have been designated as potentially responsible parties (“PRP”) under “Superfund” or similar state laws. As of December 31, 2020, ten such instances have not been dismissed, settled or otherwise resolved. In 2020, none of our subsidiaries were identified as a PRP in a new instance and no instances were settled, dismissed or otherwise resolved. In most instances where our subsidiaries are named as a PRP, we enter into cost-sharing arrangements with other PRPs. We give notice to insurance carriers of potential PRP liability, but very rarely, if ever, receive reimbursement from insurance for PRP costs. We believe that the cost of complying with the present environmental protection laws, before considering estimated recoveries either from other PRPs or insurance, will not have a material adverse effect on our results of operations, cash flows or financial condition. At December 31, 2020 and 2019, we had accruals of $0.3 and $0.2 million, respectively, relating to environmental compliance and cleanup including, but not limited to, the above mentioned Superfund sites.

In addition, this guidance modified and added other disclosure requirements, which primarily relate to valuation of Level 3 assets and liabilities. We adopted this guidance on January 1, 2020.

Costs to obtain software, including configuration and integration with legacy IT systems, coding and testing, including parallel process phases are eligible for capitalization under the new standard.

New Accounting Pronouncement or Change in Accounting Principle, Description		Clarifications in Accounting for Equity Securities In January 2020, the FASB issued ASU 2020-01, which clarifies the interactions between accounting for equity investments (ASC 321), equity method accounting (ASC 323) and derivatives and hedges (ASC 815). As a result of the ASU, when entities apply the measurement alternative to non-controlling equity investments under ASC 321, and must transition to the equity method of accounting because of an observable transaction, existing investments should be remeasured immediately before applying the equity method of accounting. Additionally, it states that if entities hold non-derivative forward contracts or purchased call options to acquire equity securities, such instruments should be measured using the fair value principles of ASC 321 before settlement or exercise. The Company early adopted this guidance on January 1, 2020, and as a result recognized non-cash gains of $11.0 million within other income in 2020 related to our investment in Flo Technologies, Inc.

New Accounting Pronouncement or Change in Accounting Principle, Description					Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, which requires lessees to recognize almost all leases on their balance sheet as “right-of-use” assets and lease liabilities but recognize related expenses in a manner similar to previous accounting guidance. The guidance also eliminates previous real estate-specific provisions for all entities. In January 2018, the FASB issued ASU 2018-01, which clarifies the application of the new leases guidance to land easements. In July 2018, the FASB issued ASU 2018-10 and ASU 2018-11, which clarify certain guidance included in ASU 2016-02 and introduces a new optional transition method, which does not require revisions to comparative periods. We adopted this standard as of January 1, 2019 using the transition method introduced by ASU 2018-11, which does not require revisions to comparative periods. We elected to implement the transition package of practical expedients permitted within the new standard, which among other things, allows us to carryforward the historical lease classification. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases. Adoption of the new standard resulted in the recording of lease assets and lease liabilities of approximately $177.2 million and $182.6 million, respectively, as of January 1, 2019. The difference between the lease assets and lease liabilities primarily relates to accrued rent and unamortized lease incentives recorded in accordance with the previous leasing guidance. The new standard did not materially impact our consolidated statements of income or cash flows. Financial Instruments—Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, which changes the impairment model for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance applies to most financial assets measured at amortized cost, including trade and other receivables and loans as well as off-balance-sheet credit exposures (e.g., loan commitments and standby letters of credit). The standard replaced the “incurred loss” approach under the current guidance with an “expected loss” model that requires an entity to estimate its lifetime “expected credit loss.” We adopted this guidance on January 1, 2020. The adoption of this guidance did not have a material effect on our financial statements.

New Accounting Pronouncement or Change in Accounting Principle, Description	Effects of Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, which provides relief from accounting analysis and impacts that may otherwise be required for modifications to agreements necessitated by reference rate reform. It also provides optional expedients to enable the continuance of hedge accounting where certain hedging relationships are impacted by reference rate reform. In January 2021, the FASB issued ASU 2021-01 which further clarifies the scope of ASU 2020-04. This optional guidance is effective immediately, and available to be used through December 31, 2022. We are assessing the impact that reference rate reform and the related adoption of this guidance may have on our financial statements.
